Joint time-delay and frequency estimation using parallel factor analysis
In this paper, the problem of joint time-delay and frequency estimation of multiple sinusoidal signals received at two separated sensors is addressed. By formulating the estimation problem with the use of the parallel factor analysis framework, the corresponding state transition and observation matrices are updated in an iterative manner according to alternating least squares, from which the ti...
متن کاملJoint time delay and frequency estimation of multiple sinusoids
In this paper, we devise a new subspace method for estimating the di erential time delay of a signal received at two separated sensors as well as the frequencies of the source signal, assuming that it consists of multiple sinusoids. The time delay and frequency estimates are related to the eigenvalues and eigenvectors of a matrix obtained from the covariances of the received signals. The e ecti...
متن کاملAnalysis of joint angle-frequency estimation using ESPRIT
High-resolution parameter estimation techniques have recently been applied to jointly estimate multiple signal parameters. In this work, we consider the problem of determining the directions and center frequencies of a number of narrowband sources in a band of interest. We present a joint angle-frequency estimation method, based on the multidimensional ESPRIT algorithm. A perturbation error ana...
متن کاملJoint estimation of DOA and time-delay in underwater localization
Joint estimation of direction of arrival (DOA) and time delay plays a great role in source localization, which attracts many researchers not only in the areas of radar, sonar, geological exploration but also in wireless communication. [1][2][3][4] M. Wax applies approximate MLE with iteration algorithm , which convert a 2-D search into two or three 1-D search. A.J.van der Veen use 2-D ESPRIT to...
متن کاملJoint angle and delay estimation
| Assuming a multipath propagation scenario, we derive a closed-form subspace-based method for the simultaneous estimation of arrival angles and path delays from measured channel impulse responses, using knowledge of the transmitted pulse shape function and assuming a uniform linear array and uniform sampling. The algorithm uses a 2-D ESPRIT-like shift-invariance technique to separate and estim...
